See you other post; the one with 1.73L N2. It shouldn't be confusing. All of these stoichiometry problems follow the same route. 1. Convert g or L to mols. 2. Use the equation to convert mols of what you have to mols of what you want. 3. Then convert back to the units you want...

Balance the equation. Convert 15.0 g Al to moles. moles = grams/molar mass. Convert 15.0 g HCl to moles. Same procedure. Convert moles Al to moles H2. Convert moles HCl to moles H2. It is likely you will obtain different answers which means one of them is wrong. The correct ...

Convert 17.8g CH4 to moles. moles = grams/molar mass. Convert 55.4g O2 to moles. Using the coefficients in the balanced equation, convert moles CH4 to moles CO2. Do the same to convert moles O2 to moles CO2. You will obtain two different answers; of course both can't be right...

This is a regular stoichiometry problem. Zn + 2HCl ==> ZnCl2 + H2 1. Convert HCl to moles. moles = M x L = ? 2. Use the coefficients in the balanced equation to convert moles HCl to moles Zn. 3. Convert moles Zn to grams. g = moles to molar mass. b) Convert moles (either Zn...

very easy math question
i doing my physics work and so i have to convert 0.0023mm to meters and it seem so easy but i not know how. i first convert it to cm, i times by ten then i divide by 100 to give me meters so i get 0.0023m but it suppose to be 2.3*10^5 m

Convert 75.0 ft^2 to cm^2. Convert 12 oz to grams. Use mass = volume x density to solve for volume, then volume = area x thickness. Solve for thickness and convert to mm.

Write the equation and balance it. Convert 62.5 g NaN3 to mols. mol = g/molar mass. Use the coefficients to convert mols NaN3 to mols N2 gas. Use PV = nRT to convert n to volume at the conditions listed.

convert the 26 miles to yards (HINT: how many yards in a mile?) convert the time to minutes (hint1: how many minutes in 2 hours, hint2..how many minutes is .23*60?

Convert 3.27 g Zn to moles. moles = grams/molar mass. Using the coefficients in the balanced equation, convert moles Zn to moles HCl. Then M = moles/L. You know moles and M, solve for L and convert to mL.

How many feet are in a mile? You can find these conversions on google by simply typing what you need to convert. For instance, "convert miles to feet" 1 mile = 5,280 feet

Are you asking if CHO is correct. No it isn't. Convert 11.4 g CO2 to grams C. Convert 4.55 g H2O to grams H2. Add the two and subtract from 5.70 g to find grams oxygen. Then convert g C to moles. moles = grams/molar mass Convert g hydrogen to moles (H atoms) = / Convert g ...
