The applicable decay formula is:N = No*e^(-kt)WhereN = Mass left after time tNo = Original massk = constantt = half lifeUsing the values given,N/No = e^(-0.1446t) = 1/2ln (1/2) = -0.1446 t *ln e^1-0.6931 = -0.1446 tt = 0.6331/0.1446 = 4.79 daysTherefore, half-life is 4.8 days.
Rounding to the nearest hundredth would equal a more accurate and precise answer since more decimals are present. Your answer would be even more accurate if you rounded to the nearest thousandth.
