Answer:
<h2>mass = 925.275 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
Density = 1.095 g/mL
volume = 845 mL
Substitute the values into the above formula and solve for the mass
That's
mass = 1.095 × 845 = 925.275 g
Hope this helps you
