How many grams does 2.2 moles of NaOH weigh?
Need total molar mass sodium hydroxide which you can easily get from your periodic table. 2.2 moles NaOH (39.998 grams/1 mole NaOH) = 88 grams in mass ==============
How many grams of v203 would you need to have 7.56e11 atoms of oxygen?
7.56 X 1011 atoms of oxygen (1 mole O/6.022 X 1023)(1 mole V2O3/3 mole O)(149.88 grams/1 mole V2O3) = 6.27 X 10 -11 grams vanadium oxide ===========================
How many grams of carbon are required to prepare 10 L of CO2 at STP?
C + O2 ==> CO2At STP 1 mole CO2 = 22.4 L 10L x 1 mole/22.4 L = 0.446 moles CO2 needed 1 mole C = 1 mole CO2 Therefore you need 0.446 moles C grams C = 0.446 moles C x 12 g/mole = 5.36 grams = 5 g (to 1 significant figure)
What is the number of moles in 54 grams of aluminum?
For this you need the atomic mass of Al. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.54.0 grams Al / (27.0 grams) = 2.00 moles Al
How many grams are there in .761 moles of Ca?
For this you need the atomic mass of Ca. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. Ca= 40.1 grams.761 moles Ca × (40.1 grams) = 30.5 grams Ca
How many grams does 2.2 moles of NaOH weigh?
Need total molar mass sodium hydroxide which you can easily get from your periodic table. 2.2 moles NaOH (39.998 grams/1 mole NaOH) = 88 grams in mass ==============
If krypton is 30.00 how many grams are their?
If the molecular weight is 30 grams/mole, you need to know the number of moles to calculate the weight. If you have 1 mole, this will yield 30 grams of krypton.
How many grams of v203 would you need to have 7.56e11 atoms of oxygen?
7.56 X 1011 atoms of oxygen (1 mole O/6.022 X 1023)(1 mole V2O3/3 mole O)(149.88 grams/1 mole V2O3) = 6.27 X 10 -11 grams vanadium oxide ===========================
