How many moles of nh3 can he produced from the reaction of 38 g of n2

fiasKO [112]

N₂ + 3 H₂ → 2 NH₃

number of moles of N₂ = 38 g / 28 g/mol = 1.357 mol

1 mole of N₂ gives 2 moles of NH₃
1.357 mol of N₂ will give ?? mole NH₃

= 2 x 1.357 = 2.7 mol NH₃

Using the atomic masses and relative abundance of the isotopes of nitrogen given below, determine the average atomic mass of nit

masha68 [24]

<span>To calculate the average mass of the element, we take the summation of the product of the isotope mass and the percent abundance. In this case, it is 0.9963 * 14.003 amu + 0.0037* 15.00 amu. This is equal to an average mass of 14.00668889 amu.</span>

7. I have 2.50 x 1023 atoms of titanium. How many moles of titanium dol<br> have?

algol13

Answer:

0.42mole

Explanation:

Given parameters:

Number of atoms of titanium = 2.5 x 10²³atoms

Unknown:

Number of moles = ?

Solution:

To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.

6.02 x 10²³ atoms makes up 1 mole of an atom

2.5 x 10²³ atoms will contain $\frac{2.5 x 10^{23} }{6.02 x 10^{23} }$ = 0.42mole
