How many moles of tungsten atoms are in 4.8 x10^25?

There are 79.7 moles of tungsten atoms in

Given the following parameter:

Moles of tungsten =

It is known that every 1.0 mole of compound or element contains Avogadro's number (6.022 x 10²³) of molecules or atoms. Hence:

1 mole = 6.022 x 10²³atoms

x = 4.8 x 10²⁵ atoms

Cross multiply:

6.022 × 10²³x = 4.8 x 10²⁵

x = 4.8 x 10²⁵/6.022 × 10²³

x = 0.797×10²

x = 79.7 moles

This shows that there are 79.7 moles of tungsten atoms in

79.7 mol.

Explanation:

Using cross multiplication:

1.0 mole of tungsten contains → 6.022 x 10²³ atoms.

??? mole of tungsten contains → 4.8 x 10²⁵ atoms.

∴ The no. of moles of tungsten contains (4.8 x 10²⁵ atoms) = (1.0 mol)(4.8 x 10²⁵ atoms)/(6.022 x 10²³ atoms) = 79.7 mol.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
