What is the mass in grams of 9.77*10^24 molecules of methanol (CH3OH)?

Chemistry

Answer:

mass of methanol = 519.3 g

Explanation:

Given data:

molecules of CH3OH = 9.77 × 10∧ 24

mass in gram = ?

Solution:

First of all we will calculate the number of moles:

(9.77 × 10∧ 24) ×  1 mol / 6.02 × 10∧23 =  16.229 moles

Now we will calculate the mass in gram:

Formula:

number of moles = mass/ molar mass

16.229 mole = mass / 32 g/mol

mass = 16.229 mol × 32 g/ mol

mass = 519.3 g

Simple method:

molar mass of CH3OH is 32 g so according to Avogadro number,

32 g of CH3OH =  6.02 × 10∧23  molecules

9.77*10^24 molecules will be equal to

(32 g of CH3OH / 6.02 × 10∧23  molecules) × 9.77*10^24 molecules

= 5.136 × 10∧-23 g/molecules × 9.77*10^24 molecules

= 519.3 g

Answer:

The increasing order of conductivity is O< Ge< Mn.

Explanation:

Electrical conductivity is defined as the measure of the ability of a material to conduct electrical current through it. The conductivity depends on the atomic and molecular structure of the material.

Metals are good conductors because they have a structure with many electrons with weak bonds, and this allows their movement instead non-metals have between four and eight valence electrons, which lack this tendency.

The conductivity increases in the periodic table from top to bottom and from right to left.

oxygen is a nonmetal therefore it is a bad conductor.

Germanium is a metalloid whose conductivity is greater than a nonmetal and worst than a metal.

Manganese is a metal,in this case, it is a good conductor.
