I would say there is 10 (2 in the ethyl group, 3 in the three methyl groups and 5 in the pent chain)
Answer: 7382 milliliters
Explanation:
1 quart = 946.35 milliliters
Therefore, 7.80 quarts • 946.35 = 7381.55
Round .55 and it becomes 7382 milliliters
Answer:
It would have a charge of +2.
Explanation:
A proton has a charge of +1, an elctron has a charge of -1, and a neutron has a charge of 0. Ignore the neurons since they have a charge of 0. Since there are 20 protons and 18 electrons (20-18), the overall charge of the atom is +2.
I think it’s something like 29.95g, sorry if it’s wrong long i haven’t done this in so long
P * V = n R T
<span>1 * 2.50 = n * 0.082 * 273 = 2. 50 / ( 0.082 * 273 ) = 0.11 mol </span>
<span>mass = mole number * molecular mass </span>
<span>mass = 0.11 * ( 16 * 2 ) = 3.52 g </span>
