molarity is the no of moles in a solute
Answer:
The answer is
<h2>0.14 g</h2>
Explanation:
To find the mass of a substance given the density and volume we use the formula
<h3>mass = Density × volume</h3>
From the question
Density = 1.122 g/L
volume = 125 mL
We must convert the volume from mL to L
1000 mL = 1 L
125 mL = 0.125 L
volume = 0.125 L
Substitute the values into the above formula and solve for the mass
That's
mass = 1.122 × 0.125 = 0.14025
We have the final answer as
<h3>0.14 g</h3>

Answer:
$55.998
Explanation:
Given data:
Total yard in blanket = 1531 yard
Price of 2.00×10² m = $7.99
Total cost for blanket = ?
Solution:
As it is given in question that,
1 yard = 0.9144 m
1531 × 0.9144 m = 1399.95 m
Total number of meters = 1399.95 m
Price of 2.00×10²(200) m = $7.99
Cost of one meter:
$7.99 / 200m = 1 m / x
x = $0.04
Now we will calculate the price of 1531 yard,
1399.95 m × $0.04 / 1m = $55.998
