Answer:

\boxed {\tt 20.317567567568 \ mL}

Explanation:

The density formula is:

d=\frac{m}{v}

Let's rearrange the formula for v. the volume. Multiply both sides by v, then divide by d.

d*v=\frac{m}{v}*v

d*v=m

\frac{d*v}{d}=\frac{m}{d}

v=\frac{m}{d}

The volume can be found by dividing the mass by the density. The mass of the object is 30.07 grams and the density is 1.48 grams per milliliter.

m= 30.07 \ g\\d= 1.48 \ g/mL

v=\frac{30.07 \ g}{1.48 \ g/mL}

Divide. Note, when dividing, the grams, or g will cancel out.

v= \frac{30.07}{1.48 \ mL}

v=20.317567567568 \ mL

The volume of the object is 20.317567567568 milliliters.

Suppose that a fictitious element, x, has two isotopes: 59x (59.015 amu) and 62x (62.011 amu). the lighter isotope has an abunda
professor190 [17]

The atomic mass of the element would simply be equal to the sum of the weighted average of each isotope, that is:

atomic mass = 59.015 amu * 0.717 + 62.011 amu * (1 – 0.717)

<span>atomic mass = 59.863 amu</span>

Why are red dwarfs not able to fuse helium to heavier elements?
ohaa [14]
Fusing helium into heavier elements requires extreme pressure and temperature. However red dwarfs' gravity is simply not enough to bring helium atom close enough to each other for fusion to occur. Therefore, red dwarfs not able to fuse helium to heavier elements.☺
