Answer:
<h2>2200 L</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 37.4 g
density = 0.017 g/L
We have
We have the final answer as
<h3>2200 L</h3>
Hope this helps you
What grade are you in? I just wanna know just to see if I learned about this
688.8g
Explanation:
Given parameters:
Number of moles = 4.2moles
Unknown:
Mass of Ca(NO₃)₂ = ?
Solution:
The number of moles of substance is convenient unit for quantifying the amount of matter therein.
It is relate to the mass of substance by the equation below:
Mass of a substance = Number of moles x molar mass
Molar mass of Ca(NO₃)₂ = 40 + 2(14 + 3(16)) = 164g/mol
Mass of a substance = 4.2 x 164 = 688.8g
