7 0

Hey there!

Cr₄(P₂O₇)₃

Cr: 4 x 51.996 = 207.984

P: 6 x 30.97 = 185.82

O: 21 x 16 = 336

-------------------------------------

                      729.804 g/mol

The molar mass of Cr₄(P₂O₇)₃ is 729.804 g/mol.

Hope this helps!

Rashid [163]

Answer:

C

Explanation:

According to the mole ratio, using 2NH3 will give you 3H2. Which means in order to find the moles of H2 you would only need to divide 2 and multiply 3 to get the amount of moles of H2 produced.

How many molecules in 3.4 moles of NH4NO3?
aliya0001 [1]

There are  20.5 x 10^24 molecules are present in 3.4 moles of NH4NO3.

<h3>How many molecules in 3.4 moles of NH4NO3?</h3>

We know that one mole of a substance has  6.022 × 10²³ molecules so in 3.4 moles of NH4NO3, we have 20.5 x 10^24 molecules if we multiply the  6.022 × 10²³ with 3.4.

So we can conclude that there are  20.5 x 10^24 molecules are present in 3.4 moles of NH4NO3.
