If troy has a 3-cm of each brass gold iron lead which cube will have the greatest mass

Chemistry
1 answer:
Shtirlitz [24]3 years ago
8 0

Answer:

The cube of gold will have the greatest mass.

Explanation:

All the cubes have the same size, so they have the same volume.

The property that varies among the cubes is density.

D = m/V     Multiply both sides by V and transpose.

m = DV

Since V is a constant, m ∝ D.

That is, the cube with the greatest density will have the greatest mass.

The observed densities are

Iron =     7.9 g/cm³

Brass =  8.5 g/cm³

Lead  = 11.4 g/cm³

Gold  = 19.3 g/cm³

Gold has the greatest density, so the cube of gold has the greatest mass.

By titration, it is found that 31.7 mL of 0.145 M NaOH(aq) is needed to neutralize 25.0 mL of HCl(aq). Calculate the concentrati
arlik [135]

Answer:

0.184 M

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

HCl + NaOH —> NaCl + H2O

From the balanced equation above, the following data were obtained:

Mole ratio of the acid, HCl (nA) = 1

Mole ratio of the base, NaOH (nB) = 1

Next, the data obtained from the question. This includes:

Volume of the base, NaOH (Vb) = 31.7 mL Molarity of the base, NaOH (Mb) = 0.145 M

Volume of the acid, HCl (Va) = 25.0 mL

Molarity of the acid, HCl (Ma) =?

Finally, we shall determine the molarity of the acid (HCl) as shown below:

MaVa /MbVb = nA/nB

Ma × 25 / 0.145 × 31.7 = 1

Cross multiply

Ma × 25 = 0.145 × 31.7

Ma × 25 = 4.5965

Divide both side by 25

Ma = 4.5965 / 25

Ma = 0.184 M

Therefore, the molarity of the acid (HCl) is 0.184 M
