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:
