Answer:
<h3>The answer is 4.15 g/mL</h3>Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 8.3 g
volume = final volume of water - initial volume of water
volume = 8 - 6 = 2 mL
So we have
We have the final answer as
<h3>4.15 g/mL</h3>Hope this helps you
<u>Answer:</u> The amount of water required to prepare given amount of salt is 398.4 mL
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
We are given:
Molarity of solution = 0.16 M
Given mass of manganese (II) nitrate tetrahydrate = 16 g
Molar mass of manganese (II) nitrate tetrahydrate = 251 g/mol
Putting values in above equation, we get:
Volume of water = Volume of solution = 398.4 mL
Hence, the amount of water required to prepare given amount of salt is 398.4 mL
