Answer:
983.84 g
Step-by-step explanation:
The following data were obtained from the question:
Density (D) = 1.04 g/mL
Volume (V) = 1 quart = 946 mL
Mass(m) =? 
The density of a substance is simply defined as the mass of the substance per unit volume of substance. mathematically, it can be expressed as:
Density (D) = mass (m) /volume (V) 
D = m/V 
With the above formula, we can obtain the mass of 1 quart of milk as follow:
Density (D) = 1.04 g/mL
Volume (V) = 1 quart = 946 mL
Mass (m) =? 
D = m/V 
1.04 = m/946
Cross multiply 
m = 1.04 × 946
m = 983.84 g
Therefore, the mass of 1 quart of milk is 983.84 g
