A student calculated the density of a sample of graphite to be 2.3 g/cm3. Show a numerical setup for calculating the student’s p
LUCKY_DIMON [66]

Answer:

Percent error = 1.5%

Explanation:

Given data:

Measured value of density of graphite = 2.3 g/cm³

Percent error = ?

Solution:

Formula:

Percent error = [Measured value - Actual value / actual value] × 100

Actual/accepted value of density of graphite = 2.266 g/cm³

Now we will put the values:

Percent error = [2.3 g/cm³ - 2.266 g/cm³ / 2.266 g/cm³] × 100

Percent error = [0.034 g/cm³ / 2.266 g/cm³] × 100

Percent error = 0.015  × 100

Percent error = 1.5%

a new weight-loss fad claims that you can reduce your mass simply by traveling to the Moon where gravity is weaker. why is this
Lilit [14]
Your mass can never change no matter where you are since mass is the amount of matter you contain.  By going to the moon, you do become lighter due to the weaker gravity but the amount of matter that you are made of (your mass) does not change.

I hope the helps.  Let me know if anything is unclear.

0.68 moles of calcium to calcium atoms​
Oksanka [162]

0.68 \: moles \: calcium \times  \frac{6.02 \times  {10}^{23} \: calcium \: atoms }{1 \: mole \: calcium} \\

The (( mole calcium ))s are simplified so the answer is based on the number of calcium atoms.

0.68 \times 6.02 \times  {10}^{23} = 68 \times  {10}^{ - 2} \times 602 \times  {10}^{ - 2} \times  {10}^{23} \\

= 68 \times 602 \times  {10}^{ - 4} \times  {10}^{23} = 40936 \times  {10}^{19} \\

calcium \: atoms = 40936 \times  {10}^{19}  \\

And we're done.

Thanks for watching buddy good luck.
