Explanation:

Given;

Number of moles of the elements = 3.8moles

Molar mass of Gold = 196.966g/mol

Molar mass of Magnesium = 24.3g/mol

Molar mass of Tin = 118.710g/mol

Molar mass of Bromine = 79.904g/mol

Mass = number of moles x molar mass

Mass of Gold = 3.8 x 196.966 = 748.5g

Mass of Magnesium = 3.8 x 24.3 = 92.3g

Mass of Tin = 3.8 x 118.710 = 451.1g

Mass of Bromine = 3.8 x 79.904 = 303.6g

Plz answer thx<br><br><br> How many moles are in 2.5 x 10^18 grams of water?

alex41 [277]

Answer:

$1.39\times 10^{17}$ moles of water in $2.5\times 10^{18} g$ of water.

Explanation:

Mass of water = $m = 2.5\times 10^{18} g$

Molar mass of water = M = 18 g/mol

Moles = n = $\frac{m}{M}$

$n=\frac{2.5\times 10^{18} g}{18 g/mol}=1.39\times 10^{17} moles$

So, there are $1.39\times 10^{17}$ moles of water in $2.5\times 10^{18} g$ of water.
