an electron has an atomic mass of 5.4 x 10-4. if a carbon atom has 6 electrons, what is the combined atomic mass of the electrons in a single carbon atom? answer in scientific notation.

0.00324 or in scientific notation  3.24×10^-3

Step-by-step explanation:

MASS OF SINGLE ELECTRON = 5.4×10^-4

MASS OF 6 ELECTRONS = 6× 5.4×10^-4

                                           =32.4×10^-4

                                            = 3.24×10×10^-4

                                             = 3.24×10^-3

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

the correct answer is $7.38
