The concentration of CH3OH in the solution is 2.18M
HOW TO CALCULATE MOLARITY:
The molarity of a solution can be calculated by dividing the number of moles by its volume as follows:
Molarity {M} = no. of moles (mol) ÷ volume (L)
According to this question, 35.0 g of CH3OH (MM = 32.0 g/mol) are dissolved in 500.0 mL of solution. The number of moles of methanol is calculated as follows:
no. of moles = 35g ÷ 32g/mol
no. of moles = 1.09mol
Molarity = no. of moles ÷ volume
Volume = 500mL = 0.500L
Molarity = 1.09mol ÷ 0.500L
Molarity = 2.18M
Therefore, the concentration of CH3OH in the solution is 2.18M
at sea level in arterial blood it is between 35 mmHg and 45 mmHg. at sea level in venous blood it is between 40 mmHg and 50 mmHg I hope this is right and helps:)
Well, it helps us categorize organisms so we can more easily communicate biological information. Taxonomy uses hierarchical classification as a way to help scientists understand and organize the diversity of life on our planet.
