Indlela yokuguqula iigram kwiimililitha? I-10 imithambo elula

Ukuguqula ukusuka kwiigram ukuya kwi-milliliters kuxhomekeke kwizinto ozilinganisayo, ekubeni ukuxinana kwezinto ezahlukeneyo kuyahluka. Nangona kunjalo, ukuba uyazi ingxinano yento ekuthethwa ngayo, ungasebenzisa ifomyula yokuguqula ngokubanzi:

Iimililitha (mL) = Iigram (g) / Ubuninzi (g/mL)

Umzekelo, ukuba ubuninzi bezinto buyi-1 g/mL, vele uhlukanise inani leegremu ngo-1 ukufumana ukulingana kwiimililitha.

Ungabona: Itheyibhile yokuxinana kwezinto ezahlukeneyo

Masithi sinolwelo olunobuninzi be-0.8 g/ml kwaye sifuna ukuguqula i-120 grams yale nto kwiimililitha. Singasebenzisa ifomula:

Kubalulekile ukuqaphela ukuba le fomyula isebenza kuphela ukuba ubuninzi bezinto eziphathekayo buhlala kwaye buyaziwa. Kwiimeko apho ukuxinana kuyahluka, kuyimfuneko ukusebenzisa iitheyibhile ezithile zokuguqulwa okanye ulwazi olunikezwa yimithombo ethembekileyo ukwenza ukuguqulwa okuchanekileyo.

Nantsi imizekelo eli-10 elula yokuguqula iigram ukuya kwimililitha ezilungele abafundi bezikolo zaseprayimari okanye zasesekondari:

1. Amanzi: Phantsi kweemeko eziqhelekileyo, ubuninzi bamanzi bumalunga ne-1 gram nge-milliliter nganye (ungayibona kwitheyibhile engentla). Ngoko ke, ukuba unama-50 amagremu amanzi, ukuguqulwa kwiimililitha, usebenzisa ifomula, kuya kuba:

IiMillilitha (mL) = Iigram (g) / Ubuninzi (g/mL) IiMillilitha (mL) = 50 g / 1 g/mL IiMillilitha (mL) = 50 mL

Ngoko ke, i-50 grams yamanzi ilingana ne-50 mL. Ngaba yaqondwa?

Kwimeko apho kukho amathandabuzo, masihambe nomnye umthambo omncinci:

2. Umgubo: Ubuninzi bomgubo bunokwahluka, kodwa ngokomyinge uqikelelwa malunga ne-0.57 grams ngemililitha nganye. Ukuba une-100 grams yomgubo, ukuguqulwa kwiimililitha kuya kuba:

IiMillilitha (mL) = Iigram (g) / Ubuninzi (g/mL) IiMillilitha (mL) = 100 g / 0.57 g/mL Iimililitha (mL) ≈ 175.4 mL (malunga)

Ngoko ke, i-100 grams yomgubo iphantse ilingane ne-175.4 mL.

Umthambo wesi-3: Guqula i-300 grams yobisi ibe yi-milliliters. Ubuninzi bobisi: 1.03 g/mL Isisombululo: Umthamo (mL) = Ubunzima (g) / Ubuninzi (g/mL) = 300 g / 1.03 g/mL ≈ 291.26 mL

Umsebenzi 4: Guqula i-150 grams yeoli kwi-ml. Ubuninzi beoli yeoli: 0.92 g / mL Isisombululo: Umthamo (mL) = Ubunzima (g) / Ubuninzi (g/mL) = 150 g / 0.92 g/mL ≈ 163.04 mL

Ukuzivocavoca 5: Guqula i-250 grams yeswekile ibe yi-milliliters. Uxinzelelo lweswekile: 0.85 g/mL Isisombululo: Umthamo (mL) = Ubunzima (g) / Ubuninzi (g/mL) = 250 g / 0.85 g/mL ≈ 294.12 mL

Umsebenzi wesi-6: Guqula i-180 grams yetyuwa ibe yimililitha. Ubuninzi betyuwa: 2.16 g/mL Isisombululo: Umthamo (mL) = Ubunzima (g) / Ubuninzi (g/mL) = 180 g / 2.16 g/mL ≈ 83.33 mL

Umsebenzi wesi-7: Guqula i-120 grams ye-ethyl yotywala kwiimililitha. Ubuninzi be-ethyl alcohol: 0.789 g/mL Isisombululo: Umthamo (mL) = Ubunzima (g) / Ubuninzi (g/mL) = 120 g / 0.789 g/mL ≈ 152.28 mL

Umsebenzi 8: Guqula i-350 grams yobusi kwiimililitha. Ubuninzi bobusi: 1.42 g / mL Isisombululo: Umthamo (mL) = Ubunzima (g) / Ubuninzi (g/mL) = 350 g / 1.42 g/mL ≈ 246.48 mL

Ukuzivocavoca kwe-9: Guqula i-90 grams ye-sodium chloride (ityuwa yetafile) kwiimililitha. Ubuninzi be-sodium chloride: 2.17 g / mL Isisombululo: Umthamo (mL) = Ubunzima (g) / Ubuninzi (g / mL) = 90 g / 2.17 g / mL ≈ 41.52 mL

Indlela yokuguqula iimililitha kwiigram

Uguqulo oluchasayo ukusuka ku-(mL) ukuya kwigrem (g) luxhomekeke kubuninzi bento ekuthethwa ngayo. Uxinaniso lunxulumano phakathi kobunzima kunye nomthamo wento. Kuba izinto ezahlukeneyo zineengxinano ezahlukeneyo, akukho fomula inye yokuguqula. Nangona kunjalo, ukuba uyazi ubuninzi bezinto, ungasebenzisa le fomula ilandelayo:

Iigram (g) = Iimililitha (mL) x Ubuninzi (g/mL)

Umzekelo, ukuba uxinano lwento yi-0.8 g/mL kwaye une-100 mL yaloo nto, ukuguqulwa kuya kuba:

Iigram (g) = 100 mL x 0.8 g/mL Iigram (g) = 80 g

Khumbula ukuba le fomyula isebenza kuphela xa ubazi ubuninzi bento ekuthethwa ngayo. Ukuba awunalo ulwazi loxinaniso, uguqulo oluchanekileyo alunakwenzeka.

Siyathemba ukuba uqonde ngendlela elula ukwenza ezi ntlobo zenguquko. Xa ufuna uncedo ngoxinaniso olwahlukeneyo okanye imithambo enzima ngakumbi, cofa ezi iitafile zokuguqulwa kweyunithi. Kuya kukunceda ngokuqinisekileyo.
