Answer:
6g/mL
Explanation:
The density, which is the mass per unit volume of an object, can be calculated using the formula;
D= m/v
Where; D = density (g/mL)
M = mass of substance (g)
V = volume (mL)
In this question, the object's mass = 15g, volume of water= 2.5 mL, d =?
Therefore,
Density = 15/2.5
Density = 6 g/mL
The object's density is 6g/mL
The number of particles that are in 12.7 moles of compound that Jessica had is 7.65 x10^24 particles of compound ( answer E)
<u><em>Calculation</em></u>
<u><em> </em></u>The number of particles are calculated using the Avogadro's Principle constant.
- that is according to Avogadro's 1 moles = 6.02 x10^23 particles
what about 12.7 moles of compound= ? particles\
by use of cross multiplication
- number of particles of compound= [12.7 moles x (6.02 x 10^23)] / 1 mole = 7.65 x 10^24 particles of compound ( answer E)
N.b moles and moles cancels each other

The complete table is as follows.
Answer: The right conjugate of is
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
For the given chemical equation:
Here, is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms which is a conjugate acid.
Thus the right conjugate of is
Answer and Explanation:
Photosynthesis reaction involves two reactants, carbon dioxide and water. These two reactants yield two products, namely, oxygen and glucose.
