Question

what is the mole fraction 5 ml of molar aqueous of 1.25 gram what is the molar fraction of 5 molar H2 so4 ​

Answer 1

Answer:

Chemical Properties of Carbon Compounds. 64. Combustion of Carbon: Carbon, in all allotropic forms, burns in presence of oxygen to form carbon dioxide with evolution of heat and light energy. In case of diamond, graphite and fullerene, they burn completely to form CO2 because they are purest form of carbon.

Answer 2

$\huge\underline\textbf{Answer:-}$

$\huge\underline\textbf{Given:-}$

$D = 1.25/ml$

This is that 1.25 solute is equal to 1 my solution:-

$Molarity = \frac{no.of \: moles \: of \: solute}{volume \: of \: sol(n)..(l)}$

$= \frac{ \frac{1.25}{10.5} }{10 {}^{ - 3} } = \frac{1250}{62.5} = 20M$

Therefore,the molarity of solution(1.25 ) is (20M)
