One fluid ounce equals 29.6 mL. One Liter contains 1000 mL. How many liters of milk should a teenager drink per day to get the recommended amount
of calcium?

Answer 1

1.0093 L

The recommended calcium intake for teenagers is 1,300 mg per day.
A glass of milk contains 305 mg Ca.
So, 305 mg Ca is contained by 1 glass of milk.
1 mg Ca is contained by 1/305 glass of milk.
1300 mg Ca is contained by 1300/305 glass of milk.
=260/61 glass of milk.
One glass milk contains a volume of eight fluid ounce = (8×29.6) mL =236.8 mL.[∵1 fluid ounce = 29.6 m L]
∴260/61 glass of milk = (260/61)×236.8 mL.
≈1009.3 mL
=(1009.3÷1000) L [∵ 1000 mL= 1L]
=1.0093 L
Therefore a teenager should drink 1.0093 L per day.
