<span>At constant temperature and moles, the answer can simply becomes P1V1 = P2V2. The original sample is 760 torr and 5.00 l, and was then compressed to 3.00 l. (760 torr)(5.00 l ) = (3.00 l)(X torr), X = 1270 torr. The new pressure exerted by helium on its container is 1270 torr.</span>
Answer:
False
Explanation:
It is the opposite. A good way to remember is the that the dependent variable depends on the independent variable.
A proper ionic formula has a cation and an anion in it; an ionic compound is never formed between two cations only or two anions only. The key to writing proper ionic formulas is simple: the total positive charge must balance the total negative charge.
The atomic weight of the naturally occurring element would
simply be the weighted average of the two isotopes. Calculating:
atomic weight = (25.2 g / mol) * 0.801 + (29.4 g / mol) *
(1 – 0.801)
<span>atomic weight = 26.04 g / mol</span>
