It is important to note that mass and mole pertain to different units of measurement, thus, 1 mole of one substance may have a lower or higher mass compared to a different substance. The mass of an object gives a measure of the number of atoms present in the substance while the number of moles of a substance refers to the amount of a chemical substance it has and is often used for chemical reactions.
For this problem, we first get the molar mass of each substance:
Molar mass of H2O = 18.0153 g/mol
Molar mass of C6H12O6 = 180.1559 g/mol
We then convert each substance into units of mass (grams), where:
1 mol H20 x 18.0153 g/mol = 18.0153 g H20
1 mol C6H12O6 x 180.1559 g/mol = 180.1559 g C6H12O6
It was then determined that 1 mole of glucose has more mass than 1 mole of water.
Answer:
Approximately 
, assuming that this gas is an ideal gas.
Explanation:
Look up the standard room temperature and pressure:
and 
.
The question states that the volume of this gas is 
.
Convert the unit of all three measures to standard units:
.
.
.
Look up the ideal gas constant in the corresponding units: 
.
Let 
denote the number of moles of this gas in that . By the ideal gas law, if this gas is an ideal gas, then the following equation would hold:
.
Rearrange this equation and solve for :
.
In other words, there is approximately 
of this gas in that .
Answer:
At low temperatures than melting point the substance remain as a solid. Then from melting point temperature to boiling point the substance will remain as a liquid. This is the temperature at which a liquid become a gas. When we increase the temperature of a liquid it will become gas at its boiling point.
Explanation:
D. The products will have more energy than the reactants.
