Calculate the density of a sample of gas with a mass of 30 g and volume of 7500 cm3.

zepelin [54]

By definition we have that the density is given by:

$D = \frac{M}{V}$

Where,

M: mass of the sample

V: volume occupied by the sample

Therefore, substituting values in the given equation we have:

$D = \frac{30}{7500}$

$D = 0.004 \frac{g}{cm^3}$

Answer:

the density of a sample of gas with a mass of 30 g and a volume of 7500 cm3 is:

$D = 0.004 \frac{g}{cm^3}$

How does the structure of the stigma aid in pollination

natali 33 [55]

Pollination is the process by which pollen is transferred to the female part of a plant. The stigma is the central part of the flower, that is supported by a style and is part of the female reproductive organ within plants. Its structure is optimised to promote pollination by having hairs, sticky surfaces and three-dimensional sculptures that capture and trap pollen.

a vehicle starts from rsst and after 10 seconds its velocity is 20m/s find the acceleration and the distance travelled.(step by

Naily [24]

Answer:

Acceleration is 2 m/s²

Distance is 100 m

Explanation:

From definition of acceleration, Acceleration is the rate of change in velocity.

• Simplifying the definition, or modifying it;

${ \boxed{ \rm{acceleration = \frac{(final \: velocity - initial \: velocity)}{time} }}}$

• Let's formulate symbols:

${ \boxed{ \rm{a = \frac{v - u}{t} }}}$

a is acceleration
v is final velocity, v = 20 m/s
u is initial velocity, u = 0 m/s [ at rest ]
t is time, t = 10 seconds

${ \rm{a = \frac{20 - 0}{10} = \frac{20}{10} }} \\ \\{ \boxed{ \rm{ \: a = 2 \: {ms}^{ - 2} }}}$

Distance = ut + ½at²

Distance = (0 × 10) + (½ × 2 × 10²)

Distance = 0 + 10²

Distance = 100 meters

What is electron affinity?

Andrews [41]

Answer:

The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion.
