Question

Will mark brainliest! How many sodium atoms are there in 26.3 grams of sodium oxide (Na2O)?

Answer 1

Answer:

${5.11 * 10^{23} atoms Na}$

Explanation:

${26.3 g} {Na_{2}O}$ * $\frac{1 mol Na_{2}O}{61.979 g Na_{2}O}$ * $\frac{2 mol Na}{1 mol Na_{2}O}$ * $\frac{6.022*10^{23} atoms Na}{1 mol Na}$

= ${5.11 * 10^{23} atoms Na}$
