lets work back. The formula to find density is d= m/v. fill in the values you know.
10 = 500/v
well, we don't need to use a calculator. dividing by ten is going to the left once, and removing one value of ten.
this means you have a volume of 50.
Hope this helps! :D
Answer:
<em>Density = 1.74 gm/mL</em>
Explanation:
Given that:
Mass of piece of Magnesium = 4.80 grams
The volume displaced by this piece = 2.76mL
Let us learn about a property:
Volume of water displaced by a substance when immersed in the water is equal to the Volume of the substance itself.
So, volume of the piece of Magnesium = 2.76 mL
To find:
Density of magnesium = ?
Solution:
Let us have a look at the formula for Density of a Substance:
Density of a substance is given as the ratio of mass of substance and the volume of that mass of substance.
i.e.

Putting the given values:

So, the answer is:
Density of Magnesium = <em>1.74 gm/mL</em>
Hello There!

<u>Answer:</u> The equilibrium partial pressure of NO is 0.0034 atm
<u>Explanation:</u>
For the given chemical equation:

The expression of
for above equation follows:

We are given:
Equilibrium partial pressure of
= 0.0159 atm
Equilibrium partial pressure of NOBr = 0.0768 atm

Putting values in above equation, we get:

Hence, the equilibrium partial pressure of NO is 0.0034 atm
