How many liters of hydrogen gas are formed from the complete reaction of 1.04 mol of C? Assume that the hydrogen gas is collecte
Alisiya [41]

The volume is 2.23 liters of hydrogen gas.

<u>Explanation</u>:

                  moles of C = grams / molecular mass of C

                                     = 1.04 g / 12.011 g/mol.

                                     = 0.086

        The ratio between C and H2 is 1 : 1

                 moles H2 = 0.086

                               V = nRT / p

                                  = 0.086 x 0.08206 x 316 K / 1.0 atm

                              V  = 2.23 L.

A solution of acetic acid and water contains 205.0 g L-1 of acetic acid and 820.0 g L-1 of water. Compute the density of the sol
LekaFEV [45]

Answer:

\rho_t=1025000 gmL^{-1}

Explanation:

From the question we are told that:

Density of acetic acid \rho_a=205 gL^{-1}

Density of Water \rho_w=820 gL^{-1}

Generally the equation for Solution Density is mathematically given by

\rho_t= \rho_w+\rho_a

\rho_t=205+820

\rho_t=1025 gL^{-1}

\rho_t=1025000 gmL^{-1}
