I’ll give the brainliest answer to whoever helps me with these!! I need them ASAP! 1. How many moles are in 3.63x10^11 atoms of Mt?

2. How many moles are in 5.96g of KNO3?

3. How many moles are in 1.50 grams of CH4?

4. How many liters are in 82.0g KBr?

1.

2.

3.

4.

Explanation:

Hello.

In this case we apply mole-mass-particles relationships by which we can consider that 1 mole of a substance equals 6.022x10²³ particles and also the atomic or molar mass of the substance to be analyzed. In such a way, for each case, we proceed as follows:

1.

2. In this case, the molar mass of KNO3 is 101.1 g/mol, thereby the moles are:

3. In this case, the molar mass of CH4 is 16 g/mol, thereby the moles are:

4. In this case, since the density of KBr is 2.75 g/mL and 1000 mL equals 1 L, the liters are:

Best regards!

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
