We know avogadro's number = 6.023 x 10²³1 amu = 1 atomic mass unit = 1/ (6.023 x 10²³) gm = 1.66 x 10⁻²⁴gramsNow, to convert amu to grams, 131.29 amu = 131.29 x 1.66 x 10⁻²⁴grams= 2.18 x 10⁻²² grams is the answer

We know avogadro's number = 6.023 x 10²³
1 amu = 1 atomic mass unit = 1/ (6.023 x 10²³) gm = 1.66 x 10⁻²⁴grams
Now, to convert amu to grams,
131.29 amu = 131.29 x 1.66 x 10⁻²⁴grams
= 2.18 x 10⁻²² grams is the answer
