Chapter 1: Q40P (page 11)

Using conversions and data in the chapter, determine the number of hydrogen atoms required to obtain1.0kgof hydrogen. A hydrogen atom has a mass of 1.0u.

Short Answer

Expert verified

The number of hydrogen atoms required to obtain1.0kgof hydrogen is6.022脳1026

Step by step solution

01

Listing the given quantities

Total mass of hydrogen is 1.0 kg.

Mass of one hydrogen atom is 1.0u.

02

Understanding the unit conversion

Unit conversion is the conversion between different units of measure for the same quantity, usually through multiplier conversion factors. One atomic mass unit is equivalent to 1.66054脳10-27. Using this conversion factor, find the number of hydrogen atoms in 1 kg of hydrogen.

03

Determination of the number of hydrogen atoms required to obtain 1.0 kg of hydrogen

Use the conversion factor to find the number of hydrogen atoms in 1kg.

1kg=1kg脳11.6605脳1027kgatoms=6.022脳1026atoms

Thus, 1kg hydrogen will have6.022脳1026atoms .
