The volume of a cylinder's formula can be used to find the area of the base.
The formula - r2 h, where r is the cylinder's radius and h is its height, determines the volume of a cylinder.
The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula r2h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. Any substance that can fill the cylinder consistently with liquid or another material may be used as the material.
The ratio of the base area to the height can be used to calculate the volume of a cylinder

The one after metamorphic rock is melting.
Gasoline is a mixture of compounds called hydrocarbons (compounds of hydrogen and carbon). It is obtained by purifying crude oil by fractional distillation. Gasoline is most commonly referred to as a mixture of compounds, therefore it is a mixture. Gasoline is composed of hydrocarbons combined with different concentrations of ethanol. <span>Pure substances can be either elements or compounds. </span>Mixtures<span> can be either</span>homogeneous or heterogeneous<span>. Another term for a </span>homogeneous mixture<span> is a solution. ... </span>Gasoline<span> is thus a blend of different compounds, so it is a </span>mixture<span>.</span>
Answer:
2.63g
This means that every mole of water molecules will contain 2 moles of hydrogen and 1 mole of oxygen atoms.
To find the percent composition of hydrogen in water, use the molar mass of water and that of hydrogen
2×1.00794g/mol18.0153g/mol×100=11.19%
This means that every 100 g of water will contain a total of 11.19 g of hydrogen. Since your sample has a mass of 23.5 g, it follows that it will contain
23.5g water⋅11.19 g H100g water=2.63 g H
