1826.5g of methanol (ch3oh), molar mass = 32.0 g/mol is added to 735 g of water, what is the molality of the methane 0.0348 m 1.13m 2.03 m 3.61 m 36.1 m navigator f10 delete backspace

Molality = 1.13 m

Explanation:

Molality is defined as the moles of the solute present in 1 kilogram of the solvent.

Given that:

Mass of = 26.5 g

Molar mass of = 32.04 g/mol

The formula for the calculation of moles is shown below:

Thus,

Mass of water = 735 g = 0.735 kg ( 1 g = 0.001 kg )

So, molality is:

Molality = 1.13 m

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
