Answer:

192.42 g [tex] CH_ {3} OH [/ tex]

Explanation:

The chemical formula of methanol is [tex] CH 3 OH [/ tex]

we calculate the molecular mass of the compound

C 12 g / mol

H 4 (1 g / mol)

Or 16 g / mol

[tex] (12 + 4 + 16) g / mol = 32 g / mol [/ tex]

We know that 1 mole of [tex] CH 3 OH [/ tex] has [tex] (6.02) 10 {23} [/ tex] molecules of [tex] CH 3 {OH] / and these have a mass of 32 g.

Now we calculate the mass of [tex] 3.62 /cdot10 {24} [/ tex] molecules of [tex] CH 3 OH [/ tex]

N(CH₃OH)=3,62·10²⁴/6·10²³ 1/mol = 6,033 mol
m(CH₃OH) = 6,033 mol · 32 g/mol (molar mass) = 193,06 g.

A sample of pure tin metal is dissolved in nitric acid to produce 15.00 mL of solution containing Sn2+. When this tin solution i

Rudik [331]

Answer:

1.00 M

Explanation:

Sn^2+ reacts with KMNO4 as follows;

5Sn^2+(aq) + 2MnO4^-(aq) + 16H^+(aq) ----> 5Sn^4+(aq) + 2Mn^+(aq) + 8H2O(l)

The number of moles of MnO4^- reacted = 42.1/1000 L × 0.145 mol/L

= 0.0061 moles

If 5 moles of Sn^2+ reacts with 2 moles of MnO4^-

x moles of Sn^2+ reacts with 0.0061 moles of MnO4^-

x= 5 × 0.0061/2

x= 0.015 moles

Since the volume of the Sn^2+ solution is 15.00mL or 0.015 L

number of moles = concentration × volume

Concentration = number of moles/volume

Concentration= 0.015 moles/0.015 L

Concentration = 1 M

Whitepunk [10]

Answer:

Where the products are H2O and Ba(NO3)2

Explanation:

A base, as, barium hydroxide (Ba(OH)2) reacts with an acid (HNO3), producing water (H2O), and the related salt (Ba(NO3)2) in a reaction called <em>neutralization reaction.</em>

The balanced reaction is:

Ba(OH)2 + 2 HNO3 → 2 H2O + Ba(NO3)2

<em>Where the products are H2O and Ba(NO3)2</em>
