Express 975,000 in scientific notation

9.75 x 10^5

A number in scientific notation has the form a x 10^b where

•a is the coefficient

•b is the exponent

Here are the steps to convert a number greater than 1 to scientific notation.

a) Find the coefficient

Put the decimal point after the first digit and drop the trailing zeroes

9.75 000

The coefficient is 9.75 .

b)Find the exponent

Count the number of digits after the first digit.

In 975 000 there are five digits after the 9. Therefore, the exponent is 5.

c)Write the number

We write 975 000 as 9.75 x 10^5.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
