Answer: 5.43x10^23 g/mole M&M's
Explanation:
1 bag of M&M's = 1.75oz (1.75oz)*(453.6g/16oz) = 49.61 g
1 bag = 55 M&M's
(49.61 g)/55 M&M = 0.9021 g/MM
1 mole M&M's = 6.023x10^23 M&M's
(6.023x10^23 M&M's)*(0.9021 g/MM's) = 5.43x10^23 g/mole molar mass
What is the empirical formula?
Answer:
Hi, There!
- ,the empirical formula of a chemical is a simple expression of the relative number of each type of atom (called a chemical element)
- Empirical formula is defined as the formula of a compound which gives the simple whole number ratio of the atoms of various elements present in one molecule of compound.
Hope this Helps!
