Round all exercises to two decimal places. Remember that quantities in scientific notation MUST comply with the rule of a x 10 ^ n where "a" is a number equal to or greater than 1 but less than 10. Remember to use the 4 steps of solving word problems. 1. How many antinomial atoms are there in 156.45 g?

2. How many moles of gold are there in 5.87 x 10 ^ 23 Atoms?

3. How many atoms of silver are there in 3.25 x 10 ^ 23 atoms?

4. How many atoms of moliben are there in 2.82 moles?

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
