Grams to moles to atoms

(41.6)g/(1 )×(1mol)/(87)g×(6.022×10^23)atoms/(1mol)

the 87 comes from the periodic table Sr has 87 as atomic weight
grams cancel then moles cancel and you are left with atoms

=2.87×10^23atoms

with all numbers it is 2.8794851×10^23atoms

Identity the step that is not part of the scientific method.
horrorfan [7]

Options:

conduct an experiment

form a hypothesis

draw a conclusion

state the cause

Answer:

'<u>State the cause'</u> is not part of the scientific method.

Explanation:

The scientific method has three wholistic steps:

  • Test the hypothesis
  • Make observations from the experiment to the hypothesis
  • Draw a conclusion or prediction from the experimental results.

A cause is neither a scientific term nor is it part of the  processes of experimentation.

I hope this was helpful.
