The mass of 1 mL of water is 1 g.
The Law of Conservation of Mass applies. For any reaction A + B = C + D The total mass of 'A' & 'B' must equal the total mass of 'C' & 'D'. Numerically, 20g(A) + 25g(B) = 45 g So the total of 'C; & 'D; must equal 45g. However, individually 'C' may be 30 g & 'D' 15g = So 30g + 15 g = 45 g as before. Now going into a reaction equation. H2SO4 + 2NaOH = NaSO4 + H2O This equation in incorrect , because you have lost mass on the right hand side These is 1 x sodium (Na) and 1 x water (H2O) missing, So mass is NOT conserved. The BALANCED equation is H2SO4 + 2NaOH = Na2SO4 + 2H2O The numbers of each type of atom are the samer on both sides of the equation ,so since atoms have mass, the balanced equation conserves mass. Hope that helps!!!!
A proton has a mass of 1 Dalton
molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g
All chemical reactions must be balanced, because matter is neither created nor destroyed in these reactions. Even if the arrangement of the individual atoms is different, the number of atoms of each element remains constant. Note that chemical reactions differ from nuclear reactions.
A 30ml solution with a mass of 45g has a density of 45/30 or 1.5 g/ml, while a 40ml solution with a mass of 50g has a density of 50/40, or 1.25 g/ml. The 30ml solution with a mass of 45g has a higher density.
15X3cmX1cmX3cmX5cm=61
45g = 0.045kg
The object's density is about 0.19 g/cm3
swagag
i think its about 43.45
The rock's density is 3 g/cm3
45 grams of water is equal to approximately 0.19 cups. This is because 1 cup of water has a mass of approximately 236.6 grams, or 0.2366 kilograms.
We need to know the density of the lotion to calculate the volume. V=M/d
There are 45g of carbohydrates in 1 cup of Jasmine (or white) rice.
Density = Mass/Volume D = M/V D = 45g/15ml D = 3g/ml
1 cup is 250 gm. So 45 gm is about 1/5 of a cup
