For addition and subtraction, round the result to match the measurement with the fewest decimal places. For example,
Mariana [72]

Answer:

7 cm

Explanation:

If the following digit is greater than or equal to 5, the decimal place is rounded up (moved up to the next number); if the following digit is less than 5, the decimal place stays the same.

4.6 + 2.35 = 6.95 cm

However, as stated in your question, cm is only being measured to the nearest 0.1 centimeters in your question.

So, you would round the digit 9 up by 1, meaning you would round it to 10. However, there are only nine digits available in our base-10 counting system, so you carry the value over,

6.95 cm could be rounded to '6. 100 cm', which is 7 cm.

How many moles of lithium are present in a sample that contains 2.45x10^87 formula units of Li2SO4?​
ddd [48]

The answer is: 8.14·10⁶³ moles of lithium are present.

N(Li₂SO₄) = 2.45·10⁸⁷; number of formula units of lithium sulfate.

n(Li₂SO₄) = N(Li₂SO₄) ÷ Na.

n(Li₂SO₄) = 2.45·10⁸⁷ ÷ 6.022·10²³ 1/mol.

n(Li₂SO₄) = 4.07·10⁶³ mol; amount of lithium sulfate

In one molecule of lithium sulfate, there are two atoms of lithium.

n(Li₂SO₄) : n(Li) = 1 : 2.

n(Li) = 2 · 4.07·10⁶³ mol.

n(Li) = 8.14·10⁶³ mol; amount of lithium atoms.
