Answer:

Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division. As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.

1826.5g of methanol (CH3OH), molar mass = 32.0 g/mol is added to 735 g of water, what is the molality of the methane 0.0348 m 1.

Snowcat [4.5K]

Answer:

Molality = 1.13 m

Explanation:

Molality is defined as the moles of the solute present in 1 kilogram of the solvent.

Given that:

Mass of $CH_3OH$ = 26.5 g

Molar mass of $CH_3OH$ = 32.04 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{26.5\ g}{32.04\ g/mol}$

$Moles\ of\ CH_3OH= 0.8271\ moles$

Mass of water = 735 g = 0.735 kg ( 1 g = 0.001 kg )

So, molality is:

$m=\frac {0.8271\ moles}{0.735\ kg}$

<u>Molality = 1.13 m</u>

A sea lab is to be designed to withstand submersion to 150 m, measured from the sea level to the top of the sea lab. Calculate t

Alchen [17]

Answer:

Explanation:

The hydrostatic pressure is defined as the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity, the formula is:

P = ρgh + P₀

Where:

ρ is density (1020kg/m³)

g is gravity (9,8m/s²)

h is depth (150m)

P₀ is the atmspheric pressure (101325 Pa)

Replacing, P = 1'600'725 Pa

I hope it helps!
