Answer:
<h2>mass = 200.23 g</h2>
Explanation:
The density of a substance can be found by using the formula
Since we are finding the mass
<h3>mass = Density × volume</h3>
From the question
Density = 0.81 g/mL
volume = 247.2 mL
Substitute the values into the above formula and solve for the mass
mass = 0.81 × 247.2
= 200.232
We have the final answer as
<h3>mass = 200.23 g to 2 decimal places</h3>
Hope this helps you
Answer:
The answer to your question is: 4.5 %
Explanation:
0.126 moles of AgNO3
mass percent = ?
mass of water = 475 g
Formula
weight percent = weight of solute / weight of solution x 100
Weight of solute
MW AgNO3 = 108 + 14 + (16 x 3)
= 108 + 14 + 48
= 170 g
170 g of AgNO3 ------------------- 1 mol
x --------------------- 0.126 moles
x = (0.126 x 170) / 1 = 21.42 g of AgNO3
Weight percent = 21.42/475 x 100
= 4.5 %
