Answer:
Empirical: OH
Molecular: 
Explanation:
First of all, we are going to use the formula: mass = no. moles x Molar Mass And rearrange it to find No. moles: No. moles = mass/Molar Mass
Let's start with Hydrogen:
The given mass is 0.44g, and hydrogen's molar mass is 1.01, therefore the number of moles is: 0.44/1.01 = 0.4356
Now we do the same for Oxygen:
Given mass = 6.92, Molar mass of Oxygen = 16.00, No. Moles = 6.92/16.00 = 0.4325
Now we identify the smaller one (Oxygen as 0.4325 < 0.4356) and we divide both values by that number:
0.4325/0.4325 = 1
0.4356/0.4325 = 1.01
We round both to the nearest 0.2 or 0.25 (depending on what you're taught), and we get: 1 and 1.
This means that the empirical formula has one of each: OH
Now to find the molecular formula we find the relative mass of OH and divide the given mass by that:
M(OH) = 16.00+1.01 = 17.01
34.00/17.01 = 2
We now multiply both by this number to get:

Out of the following choices;
A.)Divergent boundaries create mountains on which to install
the stations.
B.)Energy from magma at divergent boundaries is cleaner.
C.)Divergent boundaries are unaffected by magma convection
currents.
D.)Divergent boundaries allow heat to rise faster.
The answer is D. The two diverging convention currents bring up the heat from deep below the mantle. They act
like two cogs/pulleys that complement
each other to bring up very hot asthenospheric materials. Where a divergent boundary occurs, there also occurs a
rift such as the Great Rift Valley in East Africa.
She is brave for being compassionate for the chimpanzees and doing so much for them. She also increased support for primates. I hope this helped
