What is the concentration in molarity of a solution made using 30.0 grams of ch3oh in 300.0 ml of water?
me right ! : (

This solution has a molarity of 3.12 M = 3.12 mol/ L

Explanation:

Step 1: Data given

mass of CH3OH = 30.0 grams

Volume of the solution = 300.0 mL = 0.3 L

Molar mass of CH3OH (see periodic table)

⇒ C = 12 g/mol

⇒ H = 1.01 g/mol

⇒ O = 16 g/mol

  ⇒ 1*12 + 4*1.01 + 16 = 32.04 g/mol

Step 2: Calculate number of moles of CH3OH

Moles CH3OH = mass CH3OH / Molar mass CH3OH

Moles CH3OH = 30.0 grams / 32.04 g/mol

Moles CH3OH = 0.936 mol

Step 3: Calculate molarity of the solution

Molarity of solution = moles CH3OH / volume of water

Molarity solution = 0.936 mol /0.300 L

Molarity of the solution = 3.12 M

This solution has a molarity of 3.12 M = 3.12 mol/ L

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
