How many moles are in 135g of Teflon?
Oliga [24]

1.34 moles are in 135g of Teflon.

Explanation:

Molecular formula of teflon is (C2H4)n

mass of teflon = 135 grams

atomic mass of teflon = 100.01 gram/mole

number of moles of teflon = ?

Formula used to calculate number of moles in a substance is given as:

number of moles = \frac{mass}{atomic mass of 1 mole}

putting the values in the above equation:

number of moles = \frac{135}{100.01}

number of moles = 1.34 moles

Teflon is polymer which is used for making non-stick coating, in 135 grams of teflon there are 1.34 moles in it.

These are d-block elements.

They include the elements of group 3 to 12 in periodic table.

They have large charge to radius ratio.

They mostly form paramagnetic compounds.

They shoes more than one oxidation state.

They form colored compounds.

They all have high melting and boiling point.

They have high densities.

If an object has an acceleration of 9.8 m/s and a force of 58.8N what is the mass of an object ? What could the object be
Makovka662 [10]

Answer:

The mass of an object  is 0.6122 Kg

Explanation:

Given:

Acceleration  = 9.8 m/s

Force  = 58.8 N

To Find:

Mass of an object = ?

Solution:

We know that according to newtons 2nd law

Force is the product of the mass and acceleration

F= ma

where

F = Force

m = mass

a =  Acceleration

Substituting the values,

58.8 = m X  9.8

m= \frac{58.8}{9.8}

m = 0.6122 kg
