I’m pretty sure it’s A mid-ocean ridges
First shell hold 2. second shell can hold up to 8. so it should be 8.
Divide mass by density to determine volume. 115.384 cm^3 (unsure if you need to round.)
37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms.
I think this is the answer.</span>
