Answer:

Most higher risk volcanoes are far from California’s largest cities and several produce heat that’s used to generate electricity in what are the world’s most productive geothermal power plants, such as the Salton Buttes, 160 miles southeast of Los Angeles, and the Clear Lake Volcanic Field 85 miles north of San Francisco that powers the Geysers steam field.

How many moles are there in 5.30 x 1024 atoms of silver?

Rus_ich [418]

Answer:

The mass of

4.6

atoms of silver is approximately 820 g.

Explanation:

In order to determine the mass of a given number of atoms of an element, identify the equalities between moles of the element and atoms of the element, and between moles of the element and its molar mass.

mole atoms Ag=6.022xx10

atoms Ag

Molar mass of Ag =#"107.87 g/mol"#

Multiply the given atoms of silver by

mol Ag

6.022

atoms Ag

. Then multiply times the molar mass of silver.

4.6

atoms Ag

mol Ag

6.022
