How many moles are in 175g (Ca(NO3)2

Chemistry
1 answer:
zheka24 [161]3 years ago
6 0

Answer:

appx. 1.07 moles

Explanation:

175g of molecule Ca(NO3)2

To find the # of moles, use stoichoimetry.

1. We need the molar mass of Ca(NO3)2.

Ca mass: 40.08 g

NO3 mass: N + 3(O) --> 14.01 + 3(16.00) --> 62.01

Molar mass = Ca + 2(NO3) --> 40.08 + 2(62.01) --> 164.1 g

2. write out the calculation

175g Ca(NO3)2 * (1 mole Ca(NO3)2)/(molar mass of Ca(NO3)2)

175 g Ca(NO3)2 * (1 mole Ca(NO3)2)/(164.1 g Ca(NO3)2)

The g units cancel out and we're left with moles.

Simply perform the calculation now: 175*1/164.1 ≅1.07 moles

How many grams of H2 would be formed if 34 grams of carbon reacted with an unlimited amount of H2O? The reaction is
skelet666 [1.2K]
The balanced chemical reaction is:

<span>C + H2O → CO + H2
</span>
We are given the amount of carbon to be used in this reaction. This will be the starting point of the reaction.

<span>34 g C ( 1 mol C / 12.01 g C ) ( 1 mol  H2/ 1 mol C) (2.02 g H2 / 1 mol H2) = 5.72 g H2

Apparently, the correct answer is not in the given choices.</span>
