#[H_2O_2]~=2*mol*L^-1.........#

#"Molarity"="Moles of solute"/"Volume of solution"#
#=((6.8*g)/(34.01*g*mol^-1))/(100*mLxx10^-3*L*mL^-1)#
#=??*mol*L^-1#

Answer 3

To find the molar concentration of hydrogen peroxide, first, calculate the number of moles of hydrogen peroxide using its molar mass (34.01 g/mol). Then, divide the mass in grams by the molar mass to get the number of moles. Finally, divide the number of moles by the volume of the solution in liters (0.1 L) to get the molar concentration.

Molar mass of hydrogen peroxide (H2O2): 34.01 g/mol Number of moles of H2O2: 6.8 g / 34.01 g/mol = 0.2 mol Molar concentration: 0.2 mol / 0.1 L = 2 mol/L

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
