Alloying
Explanation:
The length of the flower garden is 529 centimeters.what is its length in meter?
The mass of 22.4 L of H2O at STP IS 18.0 grams
calculation
mass = moles x molar mas
Calculate the moles of water at STP
At STP 1 mole =22.4 L
what about 22.4 l of H2O
by cross multiplication
1mole x22.4 L/22.4 L = 1 mole
molar mass of water = (1 x2) + 16 =18 g/mol
moles is therefore = 8 g/mol x 1 mol = 18 grams
