Scoured and bleached cotton fabric was dyed with reactive dye under the following conditions:
Temperature of dyeing: 40°C
Shade: 3%
Fixation efficiency: 65%
If the rate of hydrolysis of dye is known to be 5% more for every 10°C rise in dyeing temperature, the amount of dye fixed on cotton (g of dye/kg of fibre), if dyed at 50°C accurate to one decimal place, would be
