Density is mass divided by volume
So...
D = 8/25 = 0.32 g/cm^3

Do the formula <span>D = m/v </span>

d = ( 8.0 grams ) / ( 25 c ) 

d = 0.32 grams / c

<span>d = ( 0.32 g / c ) ( 1.0 x 10^6 c / c ) ( 1 kg / 1000 kg ) </span>

d = 320 kg / c

The answer is choice C. <span>✅</span>

1. Which metal is the most reactive? How do you know this?​
Novosadov [1.4K]

Answer:

cesium

Explanation:

The most reactive metal on the periodic table is francium. However, francium is a man-made element and only minute quantities have been produced, so for all practical purposes, the most reactive metal is cesium. Cesium reacts explosively with water, though it is predicted francium would react even more vigorously.

When the alkene below is brominated with NBS reaction can occur at more than one carbon.
katrin2010 [14]

Answer:

Four products are possible.(in attachment)

2,3,4,5 carbons attached to the bromine.

Explanation:

NBS is N-bromosuccinamide which is used to brominate the allylic and benzylic positions of the compound.

Mainly used for the allylic bromination Here, four products are possible among them two are formed by the direct allylic bromination and remaining two products are formed by the rearrangement of the radical formation.

2,3,4,5 carbons of the compound are attached to the bromine.

How is carbon moved from the hydrosphere to the atmosphere?
inessss [21]

Answer:

Explained

Explanation:

the various ways of input of CO_2 into the atmosphere.

1.Dissolved  CO 2 in the ocean is released back into the atmosphere by heating ocean surface water

2.Plant and animal respiration, an exothermic reaction involving the breakdown into CO 2 and water of organic molecules.

3. Degradation of fungi and bacteria which are responsible for breaking down carbon compounds in dead animals and plants(fossils) and convert carbon into CO2 when oxygen or methane is present.

4.Combustion of organic matter (that includes deforestation and combustion of fossil fuels) oxidizing to produce CO2;

5. Cement production when calcium carbonate (limestone) is heated to produce calcium oxide(lime), cement component, and CO2 are released;

How many moles of aspartame are present in 4.50 mg of aspartame?
Alekssandra [29.7K]

Answer:- 1.53*10^-^5mol .

Solution:- Aspartame is a artificial sweetener with molecular formula C_1_4H_1_8N_2O_5 and it's molecular mass is  294.3 gram per mol.

We have been given with 4.50 mg of aspartame and asked to calculate the moles. For mass to moles conversion we divide the given mass in grams by molar mass.

Since, the mass is given in mg, we need to convert it to g first.

1 mg = 0.001 g

So, 4.50mg(\frac{0.001g}{1mg})

= 0.00450 g

Now  let's calculate the moles on dividing the grams by molar mass as:

0.00450g(\frac{1mol}{294.3g})

= 1.53*10^-^5mol

Hence, 1.53*10^-^5mol are present in 4.50 mg of aspartame.
