Answer: 0.29 grams
Since one tablet contains 14.5mg of calcium, we can find how much calcium does a bottle of 20 tablets contains by multiplying the number of tablets by the amount of calcium.
[tex]\frac{14.5\text{ mg of calcium}}{1\text{ tablet}}\times20\text{ tablets}=290\text{ mg of calcium}[/tex]Now, since we are asked to answer in grams, we will convert mg to g. To do this, we will divide the value by 1000
[tex]\frac{290\text{ mg }\times1\text{ g}}{1000\text{ mg}}=0.29\text{ g}[/tex]Therefore, a bottle of 20 tablets contains 0.29 grams
