<u>Answer:</u> The mass of water produced is 507.6 g
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of glucose = 846 g
Molar mass of glucose = 180 g/mol
Plugging values in equation 1:
![\text{Moles of glucose}=\frac{846g}{180g/mol}=4.7 mol](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20glucose%7D%3D%5Cfrac%7B846g%7D%7B180g%2Fmol%7D%3D4.7%20mol)
The given chemical equation follows:
![C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O+energy](https://tex.z-dn.net/?f=C_6H_%7B12%7DO_6%2B6O_2%5Crightarrow%206CO_2%2B6H_2O%2Benergy)
By the stoichiometry of the reaction:
If 1 mole of glucose produces 6 moles of water
So, 4.7 moles of glucose will produce =
of water
Molar mass of water = 18 g/mol
Plugging values in equation 1:
![\text{Mass of water}=(28.2mol\times 18g/mol)=507.6g](https://tex.z-dn.net/?f=%5Ctext%7BMass%20of%20water%7D%3D%2828.2mol%5Ctimes%2018g%2Fmol%29%3D507.6g)
Hence, the mass of water produced is 507.6 g
Answer:
Coefficient = 3
Subscript for Mg = 1
Subscript for Cl = 2
Explanation:
Coefficient:
A coefficient is number before the chemical formula which tells the number of molecules take part in chemical reaction.
For example:
2H₂ + O₂ → 2H₂O
In this reaction 2 moles of hydrogen react with one mole of oxygen and produce 2 mole of water. The number 2, 1 and 2 are the coefficient.
In given formula 3MgCl₂ the number before the formula which is three is coefficient.
While the number written as subscript tell about the number of atoms of elements. e.g.in MgCl₂ two atoms of chlorine and one atom of magnesium are present in given formula. If only one atom of particular element is present then it is not written as subscript.

Answer:
The wavelength of a sound is the distance between adjacent identical parts of a wave. The frequency is the same as that of the source and is the number of waves that pass a point per unit of time.
