A mole is the amount of a substance that contains as many particles as the number of atoms in 12 grams of what isotope?

Ray Of Light [21]

The SI unit for amount<span> of </span>substance<span> is the </span>mole<span>. It has the unit symbol mol. The proportionality constant is the inverse of the Avogadro constant. The </span>mole<span> is defined as the </span>amount<span> of </span>substance that contains<span> an equal </span>number<span> of elementary entities as there are </span>atoms in 12g<span> of the </span>isotope<span> carbon-</span>12<span>.

An object with the mass of 2300 g has a force of 6.2 Newton's applied to it. What is the resulting acceleration of the object?

Triss [41]

Answer:

$\boxed {\boxed {\sf a\approx 2.7 \ m/s^2}}$

Explanation:

Force is equal to mass times acceleration.

$F=m*a$

By dividing both sides by m, we rearrange the formula for a (acceleration).

$\frac{F}{m} =a$

The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.

A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².

The mass is 2300 grams, but we need to convert it to kilograms.

To convert grams to kilograms, divide by 1,000
2300 g/1000= 2.3 kg

$F= 6.2 \ kg*m/s^2\\m=2.3 \ kg$

Substitute the values into the formula.

$a=\frac{6.2 \ kg*m/s^2}{2.3 \ kg}$

Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).

$a=\frac{6.2 \ m/s^2}{2.3 \ }$

$a=2.69565217 \ m/s^2$

Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7

$a\approx 2.7 \ m/s^2$

The acceleration is about <u>2.7 meters per second squared.</u>
