it is water because it is dissolving the sodium chloride
The dimensions of field are . The area can be calculated as follows:
Converting ,
1 km =1000 m
Thus,
or,
Since, cost of new artificial turf is , thus, cost for will be:
Therefore, cost of artificial turf for field will be .
Answer:
1.90 M
Explanation:
To find the molarity of the solution, you need to use the molarity equation. This formula looks like this:
Molarity (M) = moles / volume (L)
To use this equation, you need to perform some conversions. You should (1) convert mL to L (by dividing by 1,000), then (2) convert grams NaNO₃ to moles (via molar mass), then (3) plug moles and volume into the molarity equation.
155 mL / 1,000 = 0.155 L
25.0 g NaNO₃ 1 mole
--------------------- x ----------------- = 0.294 moles NaNO₃
85.0 g
Molarity = moles / volume
Molarity = 0.294 moles / 0.155 L
Molarity = 1.8975....
Molarity = 1.90 M
Answer:
the volume of the gas will be 1/8 of the original value
