2.5 million atoms of a particular element have a mass of 8.33 x 10-16 grams. what is this element

Find the mass of one atom by:

8.33 x 10^{-16} / 2.5 x 10^{6}  = 3.32 x 10^{-22} g

Convert it into amu.
1 g = 6.022 x 10^{23} amu
so, 3.32 x 10^{-22}  x  6.022 x 10^{23}  =  200.6 amu

Now look at the periodic table and search for 200.6 amu element.
The element is Mercury (Hg)

If the volume of a gas at 0.5 atm changes from 150 mL to 75 mL, what is the new pressure?
prisoha [69]

Answer:

<h2>1 atm</h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we're finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

We have

P_2 =  \frac{0.5 \times 150}{75}  =  \frac{75}{75}  = 1 \\

We have the final answer as

<h3>1 atm</h3>

Hope this helps you
