Milk has a density of 1.04 g/mL. What is the mass (g) of 1 quart (946 mL)of milk?

1200mL

Explanation:

Mass = volume × density

= 1⋅quart × 1200⋅mL⋅quart- 1 × 1.03⋅g⋅mL −1.

We get an answer in the required units of grams, above 1200⋅g.

Note that you will have to assess whether the conversion of quart

is correct. There are imperial pints and US pints

with different volumes, and two of these may each make a quart.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

i believe the answer is true.
