A bottle of 450ml containing 10ppm of colloidal silver. Is that means that each 1ml contains 10ppm?. Thanks.
450ml
Oxygen comprises 20.946% of air... therefore, the amount of air that contains 450mL of oxygen is: (450mL) / (20.946%) = (450mL) / (0.20946) = 2148mL Paying attention to significant figures (3) the final answer is 2.15 L of air. ****P.S. Some teachers simplify the composition of air to contain only 20% oxygen. If this is the case your answer becomes 2.25L of air.
It isn't clear what unit is used for the first measurement. If you mean 1.95 liters take 450ml, then the sum is 1950ml-450ml which is 1500ml or 1.5L This is because 1 litre contains 1000ml
0.45L
450ml
450/1,000 = 45/100 = 9/20
I don't no that's what i asking you!!
450 milliliters is 15.22 fluid ounces.
