Answer:
divide the # of molecules by avogadros number and get 3.48 x 10^-6
Explanation:
Answer:
E = 3.81×10 ⁻²¹ J
Explanation:
Given data:
Frequency of photon = 5.75 ×10¹² Hz
Plancks constant = 6.626 ×10⁻³⁴ Js
Energy of photon = ?
Solution:
E = h×f
E = 6.626 ×10⁻³⁴ Js × 5.75 ×10¹² s⁻¹
E = 38.1×10 ⁻²² J
E = 3.81×10 ⁻²¹ J
Answer:
For example, given a measurement of 14.3 millimeters, plus or minus 5 percent, the relative uncertainty is 5 percent. Multiply the measurement by the relative uncertainty to obtain the absolute uncertainty. In this case, multiply 14.3 millimeters by 5 percent, which equals 0.7 millimeters
