How many moles of carbon are in 5.0 moles of ch4?

from the molecular formula of CH₄ , we see that

one molecule of CH₄ contains 1 atom of carbon  and 4 atoms of hydrogen .

in the same way , if we have 1 mole of CH₄  , it will contain 1 mole of carbon and 4 moles of hydrogen

similarly , if we have 5 moles of CH₄  , it will contain 5 x 1 mole of carbon and 4 x 5 moles of hydrogen

so in 5 moles of CH₄ , we have 5 moles of carbon

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
