67.5 grams of H2O
The water mass will be75,375 g.
The answer is 165,5 g water.
Two moles of water are produced.
i dont know help :C
The mass fraction oxygen in water is 0.8881.m oxygen = ( 0.8881 ) ( 0.18 g H2O ) = 0.16 g oxygen in 0.18 g of H2O

The answer is 165,5 g water.
Two moles of water are produced.
There are 424 grams of oxygen in 477 grams of water. 8 times 53 equals 424.
66g
If all of the quantities stated actually reacted, the law of the conservation of mass shows that the mass of carbon dioxide produced would be 40 - 18 or 22 grams.
i dont know help :C
22 grams carbon dioxide (0.5 moles)

First find the percentage by mass of oxygen in water. The formula for water is H2O, showing that water contains two hydrogen atoms for every atom of oxygen. The gram atomic masses of hydrogen and oxygen are 1.00794 and 15.9994 respectively. Therefore, the percentage of oxygen in water is 100{15.9994/[15.9994 + 2(1.00794)]} or about 88.8 %, to the justified number of significant digits; the ratio of the maximum mass of water that can be made from a given mass of oxygen is 1/0.888 or about 1.126; and the answer to the question is this number multiplied by the stated mass of oxygen, or 24.9 grams, to the justified number of significant digits.

when 60 grams of ice melts , there will be 60 grams of liquid water left.
