0.157 moles of Hg will be produced from 34.0 g of HgO.
<u>Explanation:</u>
2HgO → 2Hg + O2
Molar mass of HgO = 216.59 g / mol
34.0 g / (216.59 g / mol) = 0.156979 mol HgO
1: HgO: Hg = 1 coefficient ratio ( mol defense ) because ,
0.156979 mol HgO = 0.156979 mol Hg
= 0.157 mol of Hg.

Answer:
A, T, C y G, son las "letras" del código del ADN; representan los compuestos químicos adenina (A), timina (T), citosina (C) y guanina (G), respectivamente, que constituyen las bases de nucleótidos del ADN. ...El código genético es el conjunto de reglas que define cómo se traduce una secuencia de nucleótidos en el ARNm a una secuencia de aminoácidos en una proteína
Answer:
The number of mole is 0.04167mole
Explanation:
To convert gram to mole, we need to calculate the molecular weight of the compound
C6H12O6
C - 12
H - 1
O - 16
Molecular weight = 6 * 12 + 1 *12 + 6 * 16
= 72 + 12 + 96
= 180g/mol
To covert gram to mole
Therefore,
= 7.50g/ 180g/mol
= 0.04167 mole of glucose
