Answer:
Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅6.022⋅1023molec.
Explanation:
Answer:
probably
Explanation:
Because fossil fuel is the main fuel source, so any fuels that are not fossil fuels are alternative.
Answer:
D. 77.0%
Explanation:
% yield = actual yield/theoretical yield x 100%
% yield = 1.57 g / 2.04 g x 100%
% yield = 76.96 (round up)
Answer:
The density of ice ice is lesser than that of water that's why ice floats on water. So hence, the answer is C
