Answer:
We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.
So 1 g water will contain 1/18 moles of H2O molecules.
Now 15 g of water will contain 15/18 moles of H2O.
So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.
Explanation:
I learned this in science hope this helps.
The conclusion cannot be validated because other factors such as the amount of sunlight water location also play a vital role in germinate
Answer:
0.109 M
Explanation:
change the 974 mL to L (0.974L)
17g x molar mass (159.6g/mol)/0.974=0.109 M
