The temperature of a star is 6000K and its luminosity is 1000. Which type of star is it?

Lorico [155]

Answer:

Its probably none of those.

Explanation:

White dwarf temperatures can exceed 100,000 Kelvin according to NASA (that's about 179,500 degrees Fahrenheit). Despite these sweltering temperatures, white dwarfs have a low luminosity as they're so small in size according to NMSU.

What is the molar mass of (NH), CO?<br> 138g<br> 788<br> 968<br> 1448

aleksandr82 [10.1K]

Answer:

The molar mass of $(NH_{4})_{2}CO_{3}$ is 96.8 g/mol

Explanation:

The given molecular formula - $(NH_{4})_{2}CO_{3}$

Individual molar masses of each element in the compound is as follows.

Molar mass of nitrogen - 14.01 g/mol

Molar mass of of hydrogen = 1.008g/mol

Molar mass of carbon = 12.01 g/mol

Molar mass of oxygen =16.00 g/mol

Molar mass of $(NH_{4})_{2}CO_{3}$ is

$2\times[1(14.01)+4(1.008)]+1(12.01)+3(16.00)= 96.8g/mol$

Therefore,The molar mass of $(NH_{4})_{2}CO_{3}$ is 96.8 g/mol
