The density of titanium is 4.51 g/cm3. what is the volume (in cubic inches) of 3.9 lb of titanium?

Density of titanium is and mass given is 3.9 lb. First convert mass from pound to gram as follows:

1 lb=453.592 g

Thus,

Density of a substance is defined as mass per unit volume. Thus, volume can be calculated as follows:

Putting the values,

Converting the volume into cube inches:

Since, 1 cm=0.3937 inch

thus,

and,

Therefore, volume of titanium in cube inches will be

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

give me abc and i will get it for u.
