To calculate the concentration of the iron chloride solution, we need to convert the mass of iron chloride (200 grams) to moles using the molar mass of iron chloride (FeCl3). Then, divide the number of moles by the volume of the solution (450 ml converted to liters) to get the concentration in moles per liter (M).
A bottle of 450ml containing 10ppm of colloidal silver. Is that means that each 1ml contains 10ppm?. Thanks.
To find out how many grams are dissolved in 450mL, you can use a proportion based on the given information. The drug concentration is 17g/100mL, so you can set up the proportion: 17g/100mL = x/450mL. Cross multiply and solve for x to find the amount of drug dissolved in 450mL.
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
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.
450/1,000 = 45/100 = 9/20
0.45L
450ml
I don't no that's what i asking you!!
450 milliliters is 15.22 fluid ounces.
