Cuál será la masa molar del ácido sulfúrico, H2SO4?

98.08 g/mol

Explanation:

In order to find the molar mass of a substance, you add together the mass of the total number of moles of each element in the substance.

H2SO4 contains:

2 mol H (1.01 g/mol)

1 mol S (32.06 g/mol)

4 mol O (16.00 g/mol)

2(1.01) + 32.06 + 4(16.00) = 98.09 g/mol

Para encontrar la masa molar de una sustancia, suma la masa del número total de moles de cada elemento de la sustancia.

H2SO4 contiene:

2 mol H (1.01 g/mol)

1 mol S (32.06 g/mol)

4 mol O (16.00 g/mol)

2(1.01) + 32.06 + 4(16.00) = 98.09 g/mol

answer; /// i do believe that the correct answer is (a) boiling

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
