In 1 mole = 6.022 * 10^23 molecules of CO2
In 1.75 mole = 6.022 * 10^23 * 1.75
=10.53 * 10^23.
I hope this helps.
Answer:
The moles of ammonia present in a 1.284 g sample are 0.075.
Explanation:
Molar mass is the mass of one mole of a substance, which can be an element or a compound. If the molar mass of ammonia is 17,030 g / mol, then in 1 mole of ammonia there are 17,030 g.
So, in this case, the following rule of three can be applied: if by definition of molar mass in there are 17.030 g in 1 mole of ammonia, 1.284 g of ammonia in how many moles will it be?
moles=0.075
<u><em>The moles of ammonia present in a 1.284 g sample are 0.075.</em></u>
C. Water.
Because it is a chemical composition of two elements, Hydrogen and Oxygen elements.
Answer:
A positive ion has fewer electrons, and importantly, fewer electron shells (since atoms usually lose electrons until they get down to an empty outer shell.) This makes it smaller than a neutral atom of that element.
A negative ion has more electrons, and importantly, greater electron-electron repulsion in its outer shell. This makes it larger than a neutral atom of that element.
