Assuming the density of water to be 1 g/ml, calcu

ANSWER

The density of water is approximately 1g/ml.

Thus, 1g of water occupy volume  = 1 ml

The molar mass of water = 18 g/mol

Number of moles of water in 1g = 181 moles = 0.055 moles H2O

Now 18 g water contain = 6.022 × 1023 moleculesH2O

Thus 1 g water will have =186.022×1023 molecules H2O = 0.334  × 1023 molecules H2O

This shows that 

 0.334  ×1023 molecules H2O  will occupy volume = 1 ml

step-by-step explanation:

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.
